描述
Product Properties
Synonyms |
PC9; HCHOLA3; FH3; NARC-1 |
Source |
Mouse PCSK9 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln35-Gln694.[Accession | Q80W65] |
Molecular Weight |
Due to autocatalytic cleavage, the protein release the pro-form (59 kDa) and mature form (14 kDa). Due to glycosylation, the protein migrates to 65-68 kDa (pro-form) and 15kDa (mature form) based on Tris-Bis PAGE result. |
Endotoxin |
Less than 1EU per μg by the LAL method. |
Purity |
> 95% as determined by SDS-PAGE and HPLC. |
Activity |
SPR Data: Human LDLR, His Tag immobilized on CM5 Chip can bind Mouse PCSK9, His Tag with an affinity constant of 0.61 nM as determined in SPR assay . |
Formulation |
Lyophilized from 0.22μm filtered solution in 20mM Tris, 150mM NaCL, 200mM L-Aginine (pH 8.2). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage
The product should be stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution.
3 -6 months, -85~-65℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
